Application on mi concern:

y f lnonirson, n, of tbe limited et C riesgo, in the county of Cool; and State of illinois, have invented certain new and useful Improvements in Condensers, of which ne following is n full, clear, and exact speci- Vestion. l

invention relates to that cles of condensers in wliicli the steuin or other fluid to be condensed is allowed to ent-er passages or tubes, uguinst the outer Wells or surfaces olf which is maintained e heat absorbing vapor, and it hes more especial reference to ibut spceieof this class condensers which depend Wholly upon the heart absorbing action aqueous vapor, us contredistin-4 guislisd from vapor or nir carrying free Water moisture @ne of f -cuities in condensers s class lies been to produce aqueous in suiiicicnt quantity to cerry on the condensinga Isction without resulting in projecting superliuous Water into the tubes or psssziges olf the condenser und thereby drownins the condensing or liest absorbing action ofthe aqueous vapor.

The present invention is designed jtonyoo.

viste this diiiiculty, und has for its primary 1 ject to provide en improved und eilicieut lorni of condenser of the described class in which the necessary aqueous vapor will be generated Without the presence of any dctrlmentul amount oi :tree moisture in the tubes or passages of the apparatus.

Another object ot the invention is to provide 'the tubes or steam passages with an irnprovcd exterior formation that will greatly heut conducting preu'iertics. fw/iin vier' o the attainment of these ends und ccoinplislnncnt oi certain other objects which will appear hereinafter, the in vention consists in the licuturcs of novcltv which will now be described with ref- ,nce to 'the occoinponyi drawing. and then more particularly pointed out in the claims,

.ibntented Aug. i, fl v of thrcevhorizontal diephregms 6, 7, 8, and a bottom 9. The compartment or chamber 2 4is for the accommodation of any suitable fan or exhauster l0 mounted upon eA vertical 60 shaft l1 therein, driven from the exterior in any suitable Way, as by means of shaft l2 and bevel gears 13, 14; the compartment or chamber 3 receiving the steam or .other fluid to be condensed through one or more 65 inlet pipes l5, and the compartment, or chamber 5 receiving' the Water of condensation from vertical tubes v1G, Whose ends are expanded in the heads or diephregms 7, 8, and thereby place the chambers 3 and 5 in 70 communication. The chamber or compartment l is for the reception and expansion -pf the aqueous Vapor employed for absorbing the heat radiated by the surfaces or Wells of the tube 1G, and it receives its aqueous 75 vapor from the bottom or lower end of the `condenser through n, multiplicity of thin tubes i7, Whose ends are expended in the bottom plete 9 und bend or diolggiragm, thereby placing the compartment on, chamber l in 80 communie-tion with thc external atmospliere through the bottoni 9 ofthe condenser, and from which point the aqueous vapor is drown by thc fen or exhziustcr l0 throughu multiplicity of vertical tubes 18 85 having their ends expanded in the heads or diephrugms 6, 7, thereby placing the exhauste chamber 2 in communication with the chsinbcr il.

The operation of the fain or exhauster 90 produces fr strong ,upward current of air through the tube 17, the compartment or chamber il, und the tubes 18, und expels the sume through the top of the condenser, having :i suitable discharge flue 19, if desired, und in order that this current of oir muy bc converted into aqueous vapor before entering the condenser, l locate at the bottom of the condenser below thc inlets to the tubes 17, sonic suitable Ineens forproducing; u fine OQ spray or utoinized quantity of Water sutiiycient to saturate the air passing through the tube 17, or any other suitable ineens for causing the air to become laden with moisture Without carrying :my .appreciable amount of free Water into the tubes muy be` employed., A convenient und v"efficient construction coi'isists of a multiplicity o1" horizontoi pipes 20', closedet one end' und c0nnccted at 'the other end "lo a, header or nnini- 110 fold 2l, which supplies' ull of tbe pipes 550 with the required amount Ofi Writer :from any 65 It 'might be stated, however, that one suitable source of supply. Each of the pipes 20 is provided atsuitable intervals with nozzles or spraying roses Q2, projecting)` upwardly under-fthe tubes 17 and adapted to produce a tine spray or shower of Water conipletely underlyingthe bottom of the condenser and throughwhich t-he upward currents of air entering the tubes 17 are compelled to pass and therefore begome saturated or laden With moisture, producing what .is known as aqueous vapor. By this method, however, it Will be seen that the air entering the tube 17 is free to talre up or absorb all the moisture it can carry Without any appreciable amount dfnthe Water being` carried along with it inn) the condenser, and any small amount that should enter the lower ends of .the tubes 17 Will be free to gravitate or run,baclr as soon as the accumulation thereoi` becomes considerable or too heavy to be supported by the air currents, whereas, if the tubes Were horizontal., the Water would accumulatetherein and be drawn eventually through the condenser. This surplus Water and the Water falling from the spraying nozzles may be caught in any suitable drip pan 23.

Each of the tubes i6 is provided throughout its length with longitudinally radiating` fins 24, a multiplicity of which employed on each tube, and the heat radiating power of the tube is thereby greatly increased.l

These fins being arranged lengthwise of, the tubes permit of the free passage et' the aqueous vapor between them, and this rangement also avoids accumulation of any surplus Water between the lins. lt also avoids the formation of eddy currents or dead air spaces contiguous to the Walls of the tubes and provides for the swift passage ot' the air. in immediate contact with said Walls andttheir fins. The Water of condensation forming Within the tube 16 and the various chambers of the 'condenser will eventually find its Way into the bottom chamber through said tubes, and may be -dravvn oil' `through any suitable discharge pipe Q5, the

bottom chamber 5, if, desired, being also pro vided With pipe connection 26 whereby the air accumulatingr therein may be drawn oit or pumped out,

In the example of 'the invention shown in the drawin, the steam is preferably' adn mitted to the interiors oi the tubes 15 While the aqueous vapor is applied to the exterior, but it will nevertheless be seen that since the tubes in themselves constitute vertical passages, and in 'conjunction with the shell of the condenser they constitute additional vertical assages, it is immaterial, so far s the broat` termsiof the claims are concerned, Whether the word passage beapplied to the interior of the tube, or tothe passage formed by the eXteriors of a plurality of .the tubes,

portant adfantage to be derived from utiln order that the invent-ion may be understood by those vskilled in the art, the details ofen exempliiication thereof have been thus specifically described, but

llVhat claim as new and desire to secure by Letters atent is:
